Serial No. 367,881.

To all whom it may concern.'

Be it known that I, JOHN GORMLY, a citizen of theUnited States, residing in Philadelphia, Pennsylvania, have invented an Improved Apparatus for Treatin Solid Material, (being a division of my app ication filed October 30, 1906, Serial No. 341,233,) of Which the following is a specification.

My invention relates to the treatment of solid material of various kinds, notably ores ofthe precious metals, and it consists of an apparatus comprising a closed receptacle or a series of the same wherein suoli material may be treated under pressure, inV a vacuum or at atmospheric pressure by a special method'or process; and whereby su-ch material maybeintroducedinto such receptacle or receptacles and removed therefrom without affecting the conditions present Within'the same.

Althou hit will be understood that apparatus ein' odying my invention maybe employed for treating various materials under Widely varying conditions, where it may be desired to employ a vacuum or atmospheric.

or higher pressure, theparticular embodivment of my invention is in connection with a process of and an apparatus for cyaniding ores.

My invention is fully shown in the accompanying drawings, in which:

, Figure 1, :is a sectional View of one form of apparatus embodying my invention and capable of carr ing the improved method orprocess into e ect Fig. 2, is an elevation of 4the same on a smaller scale; Fi 3, is a sectional v'iew on the line a-a, ig. 1,; Fig. 4, is a View in elevation of another form of apparatus embodying my invention and capable of carrying out the method or process forming the subject of my companion application Fig.. 5, is an enlarged sectional view of a por-tion of the same, and' Fios. 6 and 7,' are sectional views illustrating details of the structure shown in Fig. 5'. A

In Fig. 1, -a seriesl of suitable treatin chambers or-dr'ums are indicated at A1, 2 an l3, in which, when the process of-treatment is employed in connection with ores, liirivia-tion of the Esame is carried out. These treatin 'chambers may be of any suitable t pe, suc for instance as those disclosed in t ie patent'4 'of S. T.Mufly, No.` 820,810, May 15, 1206; but as `my invention relates more particularlyto the introduction of the material to and its removal from suoli chambers, no description of the same is necessary.

At the inlet end of the apparatus, I pro- -vide a pipe 5, of suitable diameter, carrying at its upper end a funnel-shaped-hopper 6,

applied, preferably to the upper shaft, sai Wheels will be caused to' turn and trai'ferse` bucket conveyer 12 through such tubularstructure.

,VVhen em loyed in connection with the treatment o ores of the precious metals, the pipe 5 and .the tubular-structure 8 Will contain a cyaniding solution, and when the apparatus is run with pressure within the chamers 1, 2 and 3, greater than the atmos here, this li uid will occupy substantially t ie position s iown in Fig. l. The ore or other ma- 'terial to be treated is introduced into the from any suitable source (not shown) being` lhopper 6 of the pipe '5, and passes through the solution contained therein to the bottom of said pipe, thence entering the ltubulars'tructure 8 and being carried .to the top of this latter structure by the co'nveyer 12- and emptied intov the pipel 15 leading` to the chamber l.

After the material has been treated by any agent, fluid or liquid, within the chambers 1,

2 and 3, it passes to the bottom 7 a of a tubular-strucfturefSa provided with chain Wheels 9 and 10. over which a bucket conveyer 12 passes, such structure also containin a quantity of the solution through which t e mate'- rial under Vtreatment is carried by said bucket conveyer. Fromf the tubular structure 8', the material is emptied into 'a pipe 15P-and conveyed. away for further treatment, or in some instances-it ma be returned through a ipe 16, as shown 1n F` 2, to the -bottom of the tubular structure 8 or a .6.05 and communicating at its lower end with second passage through the bodies of treatf in solution and the treating chambers.

he cianiding liquid or other treating solution t rough which the solid material .is passed, forms liqluid seals at each end of the apparatus, 'there y 'preventing the entrance o the atmosphere and consequently insuring that the conditions under which the material is treated within the chambers, whether in a vacuum, under pressure, orl at atmospheric pressure, are maintained at a constant state of eiliciency.

In Figs. 4 and 5, the latter being an enlarged sectional view, I have shown a form of apparatus in which treating chambers 20, 20 20 &c., of the same general character as the-duplex tubular-structures 8 and 8, are

provided. Chain 'conv'eyers 12 are employed for passing the material under treatment continuously through -bodies of a treating liquid, or in some instances a treating Huid; in the present instance bodies of liquid be` shown. Pressure being maintained Within these chambers, the liquid will occupy substantially, the position indicated 'in Fig. 4, which shows the end chambers of such form of apparatus. In connection with this view I have also shown a feeding spout 21,

crushing mill 22, grinding'rolls 23 and la screen 24 for sifting the ore or other material before its passage to the treating apparatus forming the subJect of my invention.

Although I have shown and described bucket conveyers carried by an endless chain for transferring the material for treatment from the inlet pi e to the chambers 1, 2 and 3, and from the atter to a discharge pipe, in *the form of apparatus shown in Iig. 1, and for conveying the material entirely throu h the apparatus shown in Fig. 4, it will be o vious that other conveying means may be employed without departing from my invention, such as a belt passing over plain lpulleys and carrying buckets or other supporting elements, and .it is conceivable that under i certain conditions the material for treatment could be mechanically pushed through the treating solution or other liquid formin the seals at the ends of the apparatus, as We as through the fluid or liquid within the 'treating chambers.

By' preference one of the chain wheels or pulleys is mounted in an adjustable bearing so that any wear or stretch of the chain may Abe taken up.
